Vocabulary



Heat Transfer:movement of energy from a warmer substance to a cooler substance
Radiation:transfer of energy through empty space
Conduction:heat transfer by direct contact of particles
Convection:heat transfer by the movement of a heated fluid
Density:a measure of how much mass is in an object
Convection Current:the flow that transfers heat within a fluid


Outline



Radiation

  • transfer of energy/heat
    • transfer through empty space

Conduction

  • transfer of energy/heat
    • transfer by direct contact

Convection

  • transfer of energy/heat
    • transfer by fluids
  • transfer by convection is caused by temperature and density
    • density is measure of mass in an object
    • hot fluids move faster than cold fluids
  • fluid is heated in a cycle due to convection currents
    • convection current is the flow that transfers heat within a fluid
